Easy noise level measurement
SKF Sound Pressure Meter TMSP 1
The SKF TMSP 1 is a high quality, handheld instrument for measuring
the sound level in decibels. The environmental noise is picked up by
the microphone and then processed by the handset. The noise can be
monitored both quantitatively and qualitatively. The SKF Sound Pressure
Meter is supplied in a carrying case complete with windshield, calibration
screwdriver, jack for external outputs and an alkaline battery.
• User friendly and easy to operate, no special training required.
• dBA and dBC scale weightings for both general sound level and
low frequency noise measurements.
• Fast and slow time weighting enables either normal measurements
or the average level of fluctuating noise.
• Four different measurement scales to suit almost all situations.
• User selectable backlight for use in environments with poor lighting.
• Four digit LCD panel with both digital and bar graph display.
• Max and min function for peak measurements and alarm function
to indicate when the noise level is too low or too high.
• Tripod mounting thread for use when the instrument must remain
in the same position for a prolonged period.
